Overview

The Without Values tool allows you to efficiently filter arrays by removing specific elements using the reliable lodash _.without method. It generates a clean, new array based on your input, ensuring your original data remains unchanged during the processing.

When to use

When you need to strip unwanted items from a large dataset or configuration array.
When you want to sanitize user-provided input by filtering out blacklisted values.
When performing data cleanup tasks where maintaining the integrity of the original array is required.

How it works

1Paste your source data as a JSON array into the Array field.
2Define the specific elements you wish to exclude in the Values to Remove field as a JSON array.
3Click the process button to generate a new array containing only the remaining items.

Use cases

Cleaning up lists of IDs by removing deprecated or inactive entries.
Filtering out specific status codes from a log array for cleaner reporting.
Removing placeholder or default values from user-submitted configuration arrays.

Examples

1. Removing Inactive User IDs

Data Analyst

Background

A list of active session IDs contains several guest IDs that need to be excluded for a report.

Problem

Need to filter out specific guest IDs from a large array of active sessions.

How to use

Input the full list of IDs in the Array field and the guest IDs in the Values to Remove field.

Array: [101, 102, 999, 103, 999], Values: [999]

Outcome

The tool returns [101, 102, 103], successfully removing all instances of the guest ID.

2. Sanitizing Configuration Tags

Developer

Background

A configuration file includes a list of tags, but some tags are marked as 'deprecated' and should not be processed.

Problem

Quickly remove 'deprecated' and 'legacy' tags from the active tag list.

How to use

Paste the tag array and specify the tags to remove in the configuration fields.

Array: ["ui", "deprecated", "api", "legacy", "db"], Values: ["deprecated", "legacy"]
